[Modified moisture chamber].

BACKGROUND: Moisture chambers can protect the eye in corneal lubrication or eyelid closure disorders. However, in cases with protrusio bulbi or pronounced chemosis conjunctivae direct damaging contact of the cornea or conjunctiva on the one hand and the inside of the moisture-chamber-bandage on the other hand are possible. Since commercial moisture-chamber-bandages are not available with different internal radii, new methods are necessary to increase the distance between the bandage and the eye. MATERIAL AND METHODS: A special pressure relieving foam dressing used in the therapy and prophylaxis of decubitus was prepared in such a way that a periocular attachment was enabled and an opening for the eye was left blank. This central opening was covered with a commercial moisture-chamber-bandage. Five test persons and two ventilated patients with protrusio bulbi and manifest lagophthalmus were treated with the modified moisture chamber. The relative humidity within the bandage was measured. RESULTS: The modified moisture chamber allows an individual adaptation to the periocular shape of the face and rises the level of the monoculus for about 7 mm. The internal relative humidity was for eight hours at 98% in both test persons and patients. All test persons felt more comfortable with the modified moisture chamber on their skin. CONCLUSIONS: The presented modified moisture chamber is a derivative of the commercial monoculus bandage for patients with sensitive protrusio bulbi.

[New permanent humidity chamber in dry eye disorders].

BACKGROUND: In corneal lubrication or eyelid closure disorders it may be necessary to apply a monoculus to protect the eye from drying out. Changing the monoculus involves dermal irritation. Furthermore, because the monoculus is not completely airtight, the desired humidity is not achieved. INSTRUMENT: We introduce a tape-free permanent humidity chamber fastened to a spectacle frame that achieves a relative humidity of more than 98% even over a long period of time. PATIENTS/TESTED PERSONS: Five test persons and two patients with lagophthalmus were treated with a monoculus and with the permanent humidity chamber. Comparative measurements of the humidity achieved with the two methods were done. RESULTS: For both test persons and lagophthalmus patients the permanent humidity chamber is a good alternative to the monoculus, because it maintains a humidity of more than 98% r/H over a period of eight hours or longer. It consequently provides much better conditions for successful treatment and additionally minimizes skin irritation.
